Patent IT-MI20001429-D0 (IT)
Inventor: BOZZATO PAOLO
IPC: B04C5/06
Filed: 2000-06-26
Abstract: The invention relates to an axial feeding method of the material to be separated in a dense-medium dynamic separator ( 1 ). This method is based on the principle of imparting to the material and to the fluid in which it is dispersed, in order to facilitate introduction thereof into the separator ( 1 ), a rotational velocity component with respect to the axis of the latter, in this way the particles of material have a movement corresponding to that of the dense medium circulating in the separator, so as to prevent uncontrolled dispersion of the particles inside it. The invention also comprises a feeding apparatus ( 2 ) for carrying out the abovementioned method.

Title: Lintel
Inventor: SVENSSON LENNART
IPC: E04C3/07
Filed: 1979-08-31
Granted: 1983-06-16
Abstract: A lintel for supporting arches over doors, windows and other openings in a wall. The lintel is made of relatively thin sheet metal and has at least one load-carrying shank (5;12,13;19,20), so that the lintel in spite of its thin construction can carry great loads during the walling of the arch. The shank or each shank is provided with a longitudinally extending material weakening (6), e.g. a series of slots, perforations, a groove or similar. Said material weakening forms a fracture indication along which the shank can be folded or broken off, when the motar has set and brickwork has become self-supporting.

Title: Contactless keyboard
Inventor: ROMETSCH JOHANNES
IPC: H03K17/97
Filed: 1981-06-25
Granted: 1985-05-30
Abstract: In a contactless keyboard including for each key a transformer with a core displaceable by the key operation and including a compensation transformer common to all key the compensation transformer is so designed that with an unactuated key the signal component of the compensation transformer in the signal applied to the evaluation circuit exceeds the component of the key transformer, whereas with an actuated key the signal component of the key transformer predominates. Therefrom results a phase change of the signal applied to the evaluation circuit with the actuation of a key. The evaluation circuit compares the phase of the key output signal with that of a reference signal. For increasing the immunity from disturbance the evaluation circuit delivers an output signal (key operated or key nonoperated) only when several successive comparison operations give the same result.

Title: Rapid rate reactive sputtering of a group 4a metal
Inventor: SPROUL WILLIAM DALLAS
IPC: C23C14/34
Filed: 1983-10-27
Granted: 1988-02-25
Abstract: A metal from group IVb of the periodic table is used as the target in a reactive deposition process. An inert gas such as argon is admitted within the chamber (12) housing the target (21). Electrical power at a constant level is supplied to the target, ionizing the inert gas so that the ions bombard the metal target and initiate sputtering. A controlled flow of a reactive gas such as nitrogen is then admitted to the chamber and controlled in such a way that the metal deposition rate is not lowered. The amount of the reactive gas is constantly sampled to provide a control signal used to regulate admission of the reactive gas at the proper rate for most effective deposition of the metal onto the substrate. Closed loop systems (45, 29, 31, 43, 44, 26, 27, 39, 62) regulate the level of electrical power supplied to the target, rate of admission of the inert gas, and rate of admission of the reactive gas.
